Improvement in harvesters

Specification forming part of Letters Patent No. 112,362, dated March 7, 1871.

To all whom it may concern: Be it known that I, JOHN PELLs MANNY, of Rockford, in the county `of Winnebago and State of Illinois, have invented a new and useful Improvement in Harvesters, of which the followingis a specification: i

My invention relates more especially to the l adaptation of the machine to use as a mower;

and consists in certain improvements on the machine for which Letters Patent ofthe United States were granted to me, respectively numbered and dated 15,810, October 27, `1857,

34 703, March 25, 1862.

In the accompanying drawing, Figure 1 is aplan view of my improved machine 5 Fig. 2,

a side elevation of the same.

Theobject of the invention herein `claimed l `is to enable 'the machinegto `conform freely to undulations of the ground,` and. also to enable the driver simultaneously to rock the iinnger-beam `and to lift it parallel with the ground.

In thisinstance a driving-wheel,A, is shown as arranged `outside the frame, and fixed on a shaft, a, turning in a 'long bearing or pipe-A I box, b, fixed on a triangular frame, B, which carries suitablegearing.

The box b forms trunnions, on which a bracket, c, turns freely. They tongue O is firmly secured 4to this' bracket, and is free to vibrate up and down around the box b.

A seat, D, for the driver,lis pivoted to arms E El, and can be adjusted laterally by being made to slide on its forward pivot, d, and be held by a set-screw, or it may be adj usted latl erallyvbya slot and setscrew. The front arm, E,'is pivoted at c to a standard, E2, secured to the pipe-box b, and can be inclined backward-or forward, and held in the position desired by a slot, c1, and a set-screw. The rear arm, El, is pivoted at e2 to the tongue.

`By this `mode of construction the drivers seat is rocked backward and forward as the y nger-beam is raised or lowered, being connected rigidly with the gear-frame B through the box b. i

The finger-beam F has lugs F2 F1 projectl ing in front of its heelend, and pivoted to the vrear end of the gear-frame by joints f f.

A` lever, G, rigidly secured to the lingerbeam, extends forward over the frame within easy reach of the driver, and passes over the axle c. v

A pivoted link, G', connects the rear end of the tongue with the heel of the linger-beam.

A caster-wheel, H, supports the divider end of the fm ger-beam, ,y

The operation of the apparatus above described is` as follows: As the machine advances, the cutting' apparatus glides along the ground, its joints ff' permitting it freely to rise and fall to pass over undulating ground. Thelever G, while permitting the cutting apparatus freely to rise, prevents its descent into ditches or other sudden depressions by abutting' againstv the axle a. When the driver from his seat lifts this lever G, the cutting apparatus is tilted so that the guards incline upward, and, at the same time, the fingerbeam is raised parallel with the ground on the caster-wheel H, which serves as a fulcrum.I This parallel movement of the bar is due to the double pivots ff' and the link G', while the tilting movement is due to the relative arrangement of the gear-frame and link G', the former oscillating on the main axle and its pivots ff', while the latter oscillates on its pivots g g1. As the finger-beam rises, the drivers seat moves forward in front of the axle c, and thus counterbalances the weight ofthe finger-beam.

l Another advantage of this arrangement is, thatin boggy ground the driver can, by hooking his feet Vunder the foot-board D', draw his seat forward, and thus diminish the pressure of the cutting apparatus on the ground, or, by

pushing backward, he can temporarilyincrease the pressure of the cutting apparatusupon the ground. The seat also possesses the capacity of `being adjustable either longitudinally or laterally relatively to the line of draft.

The finger-beam may be fixed at any desired point by pins inserted in a sector-detent, g'. My machine is, of course, to be used with allthe appliances of a fully-organized mowing-machine, which are too well known to require description.

The drivers seat might be fixed on the crossing both its joint and the main axle, all tongue, and yet the lifting devices would still these parts being constructed as set forth for operate Well; but I prefer the construction I joint operation. have shown. In testimony whereof I have hereunto sub- I claim as my inventionscribed my name.

The combination of the driving Wheel, tongue, gear -frame, movable drivers seat, Witnesses: hinged finger-beam, grain-wheel, the link G', WILLIAM C, BLINN, and the lever secured to the fin ger-beam, und LEWIS A. WEYBURN.
